WATER- ^SPI:TGIFICA'IIOlY `forming part of `Letters Patent No. 413,671, dated October 29, 1889.

Application filed August 16, 1888. Serial No. 27713612. (No model.)

s To all whom ift/,may concern.-

Be it known that we, OMAR H. JEWELL and i fss l from;

residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and'usefullmprovement inWater-Filters,

which is fully set forth in the following speci.V

fication,'referen'ce being had to the accompanying drawings, in whichv Figure 1 is a sectional view of an apparatus embodying our invention, taken` on the line 1 l of Fig. 2; Fig. 2, a plan section taken on the line 2 2 of Fig. 1 Fig. 3, a detail sectional view of one of the injector-nozzles and 'its check-Valve, and Fig. 4 a detail sectional View of the'chemicahtank and its connections. Like letters refer tolike parts in all the figures of the drawings.

Our invention relates to iiltering apparatus, and more particularly to that class' in which the water to be ltered'is forced through the sand, gravehor other, suitable filtering medium in order to remove the impurities there- Our present inventionl is vin the nature of an improvement upon the apparatus set forth in'Letters Patent Nos. 377,387 and 377,388, granted February 7, 1888,'to Omar H. Jewell, and has forits obj ect to increase the efficiency of the apparatus therein shown and described, and at the same time to simplify the construction. j ,n n s To these ends our invention consists in certain novel features, whichwe will now proceed to describe, and will then particularly point out in theclaims. i y

In 'the drawings, A representsthe filtertank, which is closed both at the top and bot- 1 toni, and is lled withsand, gravel, or other suitable iilteringmaterial. At some suitable point on this tank, and preferably at the side thereof, there is arranged a valve-chest B,withl which all'thevarious pipes of the filter are connected.` This 'valve-chest is preferably connected to the iilterftank A by means of a suitable saddle b, bolted tothe tankand carrying the base b of the valve-chest. To the front ofthis base" there is attached the valve-A Seat b2, 4which is. preferably constructed of brass or other lnon-corrosive material, and in front of this` valveyseat is arranged the body b3 of the valve-chamber, which is closed at its front end by means of a cap or cover b4. The

whole valvechest is secured vtogether by means of suitable bolts b5, or in any other suitable manner. i

B represents a strainer constructed of Y la chemical-tank E, constructed of glass or other suitable material, and having at its lower end a pipe E', leading to the horizontal portion of the pipe D, and provided with a suitable valve e. From the top of the chemical-tank E a pipe E2 leads to the upright. portion of the pipe D, said pipe E2 being provided with a valve e.

c2V indicates a vsuitable filling-plug, which may be removed in order to fill the chemicaltank, said plug being subsequently replaced to close the same when Iilled.

The valve-chest B is provided withV lfour ports f, j', f2, and f3, and there is arranged within the said valve-chamber a slide-valve G, provided on its inner face with a groove g, of sufficient length to connect either the ports f and f or the ports f and f2. The said valve is also provided at its lower endy with an eX- tension g', which, when the valve is in the position shown in Fig. 1, will close the lower port f3. The valve G is operated by means of a valve-rod G, which is threaded at its upper end and passes through a Hsuitablythreaded hand-Wheel G2, by means of which the said valve may be moved in la vertical direction. A suitable stuffing-box g2 isprovided at the point where the valvelrod passes y loo ward from the port f and connected to the pure-water and waste pipes, in the manner hereinafter described.

F2'indicates an outlet-pipe connected to the port f2, and extending into the filter-tank A, and downward therein almost to the bottom.

F3 indicates a wash-pipe connected to the port f3, and extending into the filter-tank, and then downward almost to the bottom of the same.

The pipe F is provided with a three-way' valve H, by means of which it may be connected either to the pure-water-supply pipe H or to the waste-pipe H2. This three-way valve consists of a suitable casing h, connected at one end to the pipe F and at the other end to the pipe H, the pipe H2 being connected to it at a point intermediate between the two, as shown. A transverse diaphragm h', provided with a suitable valveaperture, passes diagonally across the interior of the valve-casing, and a similar valveaperture is formed in the casing at the point which the waste-pipe H2 is connected to the same, this latter` valve-aperture being arranged immediately opposite the former one. h2 indicates a valve adapted to close either of these valve-apertures, being provided with a threaded valve-stem h3 and wheel h, by means of which it is operated in the usual manner.

The pipe F2 is provided at its lower end with a screen fi, which serves to prevent the entrance of sand or other substances into the pipe. From the lower end of the pipe F3 branch pipes J radiate outward, siX of these branch pipes being shown in the present instance, although any desired number may be employed. The outer end of each branch pipe J is turned upward, as shown, and is provided with a jet-nozzle j, in the rear of which is arranged a check-valve j', which serves to prevent the entrance of sand into the said pipe.

In conjunction with the radiating branch pipes J we employ a corresponding series of what are known as siphon-pipes K, extending upward from the nozzles therein to the top of the tank and being there bent downward, as shown. Each pipe K is supported on a suitable cage K the upperend of which incloses and is contracted around the nozzle j, as shown at k.

L indicates an outlet-pipe arranged at the lower end of the cap of the valve-chest B in front of the screen B therein, the same being provided with a valve l, by means of which it may be opened or closed, as desired.

The operation of the apparatus is as follows: Vhen in the act of filtering, the parts of the apparatus are in the position shown. The water to be filtered is drawn from any suitable course through the suction-pipe C by means of the pump C, and is forcedV thence through the supply-pipe D into the valvechamber. During its passage through the said supply-pipe it takes up from the chemical-tank E the necessary amount of the chemical contained therein. The amount of the chemical delivered is controlled by means of the valves e and e', the connection of the pipes E and E2 being such that a pressure due to the action of the pump is equalized on both the top and bottom of the tank, allowing the chemical contained in said tank to pass downward into the supply-pipe B and to mingle with the water contained therein. As the Water from the supply-pipe D enters the valve-chamber it must first pass through the screen B', which serves to prevent any large objects from entering the valve-chamber proper, and thus clogging the ports or injuring the valve or preventing its operation. The pipe L serves to remove these large objects and clean out that portion of t the valve-chamber in front of the screen'.4 Passing th rough the valve-chamber, the Water enters the port f, and, passing through the pipe F, enters the filtering-chamber at the top thereof. It is then forced down through the filtering material contained in the tank, and, passing through the screen t', enters the outlet-pipe F2, whence it passes through the port f2, the' groove g in the valve G, and the port f to the pipe F. The valve h2 being in the position shown, the filtered Water passes into the pure-water pipe H, and vis thence delivered to the desired point or points. NVhen the filtering material in the tank -has become clogged and it is desired to wash the same, this operation is performed by rotating the hand-Wheel G2. until the valve G is brought into position with its groove g connecting the port f and f When in this position, the downward extension g of the said valve will close the port f2 and the port f3 will be opened. The Water supplied by the pump will then pass through the said port f3 into the Wash-pipe F8 and through the branch pipes J thereof, escaping in the form of a jet through the nozzles j. This jet, entering the Siphon-pipes k,Will draw along with them the filtering material, and will carry the same upward through the said pipes and discharge it at the top of the tank. This operation continues until the filtering material is thoroughly washed and the impurities passing off with the waste water, which escapes through the pipe F, port f, groove g in the valve G, and port finto the pipe F. During this operation of Washing, the valve h2 is moved into a position to close the pure-Water pipe H and open the Waste-pipe H2, through which the wash-water escapes and is discharged at any desired point.

It will be seen that by the employment of a slide-valve in connection With a valve-chamber provided with suitable ports, to which chamber all of the various pipes of the filter -are connected, we are enabled by the movement of this single valve to shift the apparatus from the filtering to the Washing position, the only additional change necessary being the shifting of the valve h2. The appa- IOO IIC

ratus is thus greatly simplified both in its construction and operation, and we are ena' bled to dispense .with a great number of the valves hitherto employed.

The construction and arrangement of v the chemicaltank relatively to the supply-pipe forms a simple and at the same time efficient means for supplying chemicals to the Water,

if desired.`

'.The washing apparatus within the tank serves to thoroughly agitate and cleanse the vention, and we therefore do not Wish to be understood as limiting ourselves strictlyv to the precise details hereinbefore described, and shown inthe drawings. v y Having thus described our invention, what weclaiin as new, and desire to secure by LettersPatent, is.- 1 A l 1. In a water-filter, the filter-tank, in combination with the valve-chest, the sliding valve G, arranged therein and recessed as described, the IWater-supply pipe opening into l Y said valve-chest on one side of the valve,` the four ports, `and the four pipes connected 'to said ports, three of them-to wit, the washpipe and inlet and outlet pipes-extending into the tank, andv the fourth connecting with the pure-water and waste pipes, substantially.

" l as and for the purposcsspecied.
